Control the weather in the Rain Room at the Curve, Barbican Centre, London

Visitors walk through an art installation called the Rain Room in The Curve
gallery at the Barbican Centre in London. The Rain Room is a 100 square
metre field of falling water which visitors are invited to walk into.
Sensors detect where visitors are standing, and the rain stops around them,
giving them an experience of how it might feel to control the rain.
